[fedora-java] ant with jdk5

Hi there,
I filled Bug 601830 about this problem we were discussing on the users list. So far it looks like
xerces-j2 was built for Fedora-13 using OpenJDK6 but without a target directive, and thus requires
Java >= 1.6.0. This prevents me from running Apache Ant using Sun JDK 5 (repackaged by JPackage
standards).
I hope the mantainer decides this is worth to fix and release a new xerces-j2 package compatible
with at least Java 1.5.0. In the mean time:
- What is class data version 45.3 (from log4j.jar)?
- How to install (from Fedora or JPackage repos) an jaxp_parser_impl.jar / Xerces J2 complied for
JDK 5m if there is such a thing?
- If there isn't, where should I change the SPEC from xervers-j2*src.rpm to rebuild it using Sun
JDK5 or to add target=1.5.0?
- How can it be that ant runs fine using gij which in theory supports only Java 5, but not with Sun
JDK 5?
